Phase diagram of the bose Hubbard model
The first reliable analytic calculation of the phase diagram of the bose gas on a d-dimensional lattice with on-site repulsion is presented. In one dimension, the analytic calculation is in excellent agreement with the numerical Monte Carlo results. In higher dimensions, the deviations from the Monte Carlo calculations are larger, but the correct shape of the Mott insulator lobes is still obtai...
متن کاملMean-field phase diagram of the one-dimensional Bose gas in a disorder potential
We study the quantum phase transition of the 1D weakly interacting Bose gas in the presence of disorder. We characterize the phase transition as a function of disorder and interaction strengths, by inspecting the long-range behavior of the one-body density matrix as well as the drop in the superfluid fraction. We focus on the properties of the low-energy Bogoliubov excitations that drive the ph...
متن کاملPhase Diagram of a Polarized Fermi Gas
The polarized Fermi gas, which has recently been realized in ultra-cold atomic gases where the number of atoms in the two spin states is different, has attracted many experimental and theoretical works. This paper introduces the phase diagram of the polarized Fermi gas at T = 0 and at finite temperature as well. Open questions that haven’t been solved are pointed out and available experiments a...
متن کاملTwo-step condensation of the charged Bose gas.
The condensation of the spinless ideal charged Bose gas in the presence of a magnetic field is revisited. The conventional approach is extended to include the macroscopic occupation of excited kinetic states lying in the lowest Landau level, which plays an essential role in the case of large magnetic fields. In that limit, signatures of two diffuse phase transitions (crossovers) appear in the s...
متن کاملPhase ordering kinetics of the Bose gas.
We study the approach to equilibrium of a Bose gas to a superfluid state. We point out that dynamic scaling, characteristic of far from equilibrium phase-ordering systems, should hold. We stress the importance of a nondissipative Josephson precession term in driving the system to a new universality class. A model of coarsening in dimension d52, involving a quench between two temperatures below ...
